Soft Printed Circuit Board Advantages and Applications in Electronic Manufacturing

Printed circuit boards (PCBs) are commonly found in electronic devices as they serve several functions. Think of them as the brain of electronic devices. There are many types of circuit boards, and which one is right for a particular device is based on the applications and environment of the final product.

A soft PCB is also known as a flexible printed circuit board. It is a circuit board that can bend, fold, or twist depending on what capabilities are required of the electronic device. This circuit board is an innovative invention in the electronic industry as it serves many purposes. A soft PCB is lightweight and flexible; however, the processing of this circuit board requires further protocols like material handling, special clamping, and experienced electronic manufacturers.

Benefits of Soft Printed Circuit Boards

Soft PCBs offer many benefits. These circuit boards aren’t just flexible, they have unique features making them essential in the electronic industry. Some of these benefits include:

Light weight

Soft PCBs are lightweight, often created from plastic or epoxy. Soft circuit boards don’t feature substrate cores. Their low weight is a result of the surface mount technology (SMT) components on them. In addition, soft PCBs are composed of very thin substrate materials.

Small Size

One of the biggest advantages of a soft PCB is its size. This circuit board can be built to fit into compact spaces with an ability to adjust. Another advantage of a soft PCB is it contains negligible width, much like paper.

Resistance to High Temperature

Soft PCBs can resist high temperatures, making them ideal for the oil and gas sector. In these sectors, rigid boards can easily melt out. The ability of soft PCBs to withstand varying high temperatures depends on the material used during fabrication.

Improved Capability

There’s a common misconception that soft PCBs don’t possess the same capabilities as rigid boards because of their flexibility. However, soft circuit boards have excellent ability to perform in many applications as they improve the general performance of electronic devices by enhancing component density.

High Durability

Soft PCBs, when treated well, can stand the test of time. These boards are extremely durable since their manufacturing takes place under precise conditions. Also, these boards are usually coated with formulated materials.

More Than Design


Soft PCBs integrate fewer mechanical connectors. Also, there’s a minimal use of interconnection points, proving the system to be more reliable. Furthermore, a soft PCB enables increased heat dissipation, and that can be very beneficial in many devices.

Applications of Soft Printed Circuit Boards

While not as common as rigid PCBs, soft PCBs are regularly used in certain applications. These include:


Soft PCBs are commonly used in smart watches, spy microphones, and compact cameras. Soft PCBs have proven to be very useful in the production of wearable devices including those in the medical industry.


Printers utilize soft PCBs because they offer a pathway to link signals with the arm of the disk drive.

Consumer Electronics

Soft PCBs are ideal for use in consumer electronics like smart phones, calculators, and entertainment devices.

Medical Devices

Soft PCBs are also ideal for some medical devices, especially wearables. Soft PCBs are found in heart monitor devices, body-mounted sensors, and fitness trackers. Patients wear these devices to regulate and monitor specific ailments in the body, so PCBs in medical devices have to stand up to constant wear and remain precise and reliable.


Some industrial devices include soft boards. Soft PCBs are perfect for use in the production of robotic arms, barcode equipment, and processing machines.

Flexible PCBs are ideal for use in main electronic sectors, like wearables, telecommunications, medical devices, aerospace, and automotive among many others.
